TECHNICAL FIELD AND BACKGROUND OF THE INVENTION

[0002] This invention relates generally to security systems for vehicles
and, more particularly, to remotely actuated, personal safety lighting
systems. The invention is particularly adapted to incorporation in the
exterior mirrors of a vehicle.

[0003] Personal security in and around vehicles has become an important
concern. In particular, an increasing number of assaults and robberies
are committed in parking lots while occupants are entering and exiting
vehicles. While remote-operated, keyless entry systems have been
incorporated in vehicles in order to unlock the vehicle and illuminate
interior lights, such systems merely expedite entry to the vehicle and do
not, per se, enhance security around the vehicle. Accordingly, a need
exists for a vehicle security system to increase the security for vehicle
occupants while entering and exiting the vehicle. Any such system would
need to be aesthetically pleasing and not burdensome in use.

SUMMARY OF THE INVENTION

[0004] The present invention is intended to provide a personal safety
feature for a vehicle in the form of a floodlight adapted to projecting
light generally downwardly on an area adjacent a portion of the vehicle
in order to create a lighted security zone in the area. Advantageously,
the floodlight is preferably positioned in the housing of an exterior
mirror having a reflective element also positioned in the housing.
According to an aspect of the invention, an actuator is provided for the
floodlight including a base unit in the vehicle and a remote transmitter.
The base unit is responsive to a signal from the remote transmitter in
order to actuate the floodlight. This allows the vehicle operator to
actuate the floodlight from a distance in order to establish the security
zone prior to approaching the vehicle.

[0005] According to another aspect of the invention, an actuator for the
floodlight includes a lockout device in order to prevent actuation of the
floodlight during operation of the vehicle. According to yet a further
aspect of the invention, a signal light that is adapted to projecting
light generally rearwardly of the vehicle is included in the exterior
mirror housing. An actuator for the warning light is connected with the
stoplight circuit, turn signal circuit, or both the stoplight and turn
signal circuit, of the vehicle in order to actuate the warning light when
either the stoplight or turn signal is being actuated.

[0006] According to yet another aspect of the invention, the floodlight is
adapted to projecting a pattern of light from the housing on an area
adjacent a portion of the vehicle that extends laterally onto the vehicle
and downwardly and rearwardly of the vehicle. In this manner, a security
zone is established from the vehicle door to the rear of the vehicle. The
signal light is adapted to projecting a pattern of light extending
laterally away from the vehicle and rearwardly of the vehicle. In this
manner, the pattern generated by the signal light cannot be substantially
observed by a driver of the vehicle. However, the pattern generated by
the signal light may be observed by a driver of another vehicle passing
the vehicle equipped according to the invention.

[0007] The floodlight and signal lights may be generated by a light
emitting diode positioned in the housing, a vacuum fluorescent lamp
positioned in the housing, an incandescent lamp positioned in the housing
or a light source in the vehicle and a light pipe between the light
source and the mirror housing.

[0008] By providing a lighted security zone adjacent the vehicle, users
can observe suspicious activity around the vehicle. The pattern of light
generated by a security light according to the invention establishes a
security zone around, and even under, the vehicle in the important area
where the users enter and exit the vehicle. The provision for remote
actuation of the security light provides a deterrent to ward off persons
lurking around the protected vehicle while the users are still at a safe
distance from the vehicle. The provision for a lockout circuit ensures
that the Security light will not inadvertently be actuated while the
vehicle is in motion. The invention, further, conveniently combines a
signal light that acts in unison with the vehicle's turn signal, brake
light, or both, with the security light in an exterior mirror assembly.
The signal light may be designed to be observed by other vehicles passing
the equipped vehicle but not directly by the driver of the equipped
vehicle.

[0009] The present invention further provides an exterior mirror system
for a vehicle, which incorporates a signal light into the exterior
rearview mirror assembly. The signal light provides a light pattern which
preferably extends forwardly, rearwardly, and to the side of the vehicle
in order to provide advance warning to approaching vehicles, or to a
vehicle that is in the vehicle's blind spot, that the driver of the
vehicle intends to make a turn or lane change, with the light pattern
preferably restricted from direct observation by a driver of the vehicle.
Additionally, the present invention provides a "powerfold" exterior
mirror system which includes a security light that projects a pattern of
light adjacent side of the vehicle and fans the light outwardly from the
vehicle to provide a security zone, which is optionally adapted to
maintain the position of the pattern of light even when the exterior
rearview mirror assembly is moved between its normal extended operating
position to a folded position. It is quite common in vehicles in many
European countries to have electrically retractable or "powerfold"
mirrors.

[0010] According to one form of the invention, an exterior mirror system
for a vehicle includes an exterior mirror assembly, which includes a
reflective element, a housing for the reflective element, and a
positioning device for adjusting the position of the reflective element
in the housing. The mirror assembly is adapted to mount to the vehicle
and includes at least one signal light. The signal light includes a light
source and a light conduiting member. The light conduiting member is
oriented for facing at least rearward of the vehicle and is adapted to
project a pattern of light from the housing which extends at least
rearwardly of and laterally from the vehicle and to restrict the light
from extending into the vehicles so that a driver seated in the vehicle
does not directly observe the pattern of light. Preferably, the pattern
of light comprises an amber colored light to provide a signal.

[0011] In one aspect, the light conduiting member includes a light input
surface and a light emitting surface. In one form, at least a portion of
the light emitting surface is generally orthogonal to the light input
surface. In further aspects, the light conduiting member includes a
plurality of light conduiting portions with each including a light input
surface and a light emitting surface and first and second side walls. The
side walls provide internal light reflecting surfaces and direct light
from the light source through the light conduiting portions and through
said light emitting surfaces. In preferred form, the signal light
includes a plurality of light sources, with each being associated with
the light conduiting portions.

[0012] In other aspects, the light conduiting member includes a first
side, a first end, and a second side. The first side defines the light
emitting surface and is positioned for facing outward from the housing.
The first end defines the light input surface. The second side defines a
plurality of internal reflecting surfaces which are arranged to reflect
the light from the light source through the first side of the light
reflecting member and in the light pattern. In further aspects, the light
pattern includes a plurality of light regions, with each of the light
regions having a first leading edge generally parallel with the vehicle
and a second leading edge generally angled away from the vehicle. For
example, the internal reflecting surfaces may comprise generally angled
planar surfaces provided on the second side of the light conduiting
member.

[0013] In another aspect, the exterior mirror system includes a second
light conduiting member which is positioned in a front facing portion of
the housing wall of the exterior mirror assembly and directs light at
least forwardly of the vehicle. Preferably, the second light reflecting
member wraps around an outer portion of the housing wall for directing
light laterally with respect to the vehicle.

[0014] According to yet another form of the invention, an exterior mirror
assembly for vehicle includes a mirror housing having a reflective
element and a positioning device for adjusting the position of the
reflective element, and a signal light mounted to a portion of the
assembly. The signal light includes a light source and a reflector, which
includes a plurality of faceted light reflecting surfaces for directing
light from the light source forwardly, rearwardly, and laterally of the
vehicle. The faceted reflecting surfaces are adapted to restrict light
from extending into the vehicle so that a driver seated in the vehicle
does not directly observe the pattern of light.

[0015] In one aspect, the faceted reflector surfaces may comprise either
planar reflective surfaces, concave reflective surfaces, or convex
reflective surface. Preferably, at least one of the faceted reflective
surfaces comprises a concave reflective surface.

[0016] In other aspects, the signal light includes a housing, which
includes a recessed portion defining a curvilinear wall. The light source
is positioned in the recessed portion, and the reflector is positioned
along the curvilinear wall. Light emitted from the light source is
directed outwardly from the light module and forwardly, rearwardly, and
laterally of the vehicle and is restricted from extending into the
vehicle so that the driver seated in the vehicle does not directly
observe the light pattern.

[0017] According to another form of the invention, the exterior mirror
assembly for vehicle includes a powerfold exterior mirror system. The
powerfold exterior minor system includes a folding portion and a
non-folding portion, with the non-folding portion being adapted to mount
to the vehicle, and the folding portion including a reflective element
and being adapted to move between a normal viewing position and a folded
position. At least one security light is substantially positioned in
either the folding portion or the non-folding portion, which is adapted
to project a pattern of light from the exterior mirror assembly to create
a lighted security zone in an area adjacent the vehicle.

[0018] In one aspect, the security light is positioned in the folding
portion of the exterior mirror assembly. In further aspects, the exterior
mirror assembly further includes an actuator, which adjusts the position
of the security light in the folding portion when the folding portion
moves to its folded position whereby the orientation of the lighted
security zone remains substantially unaffected by the movement of the
folding portion.

[0019] In another aspect, the security light is mounted to the non-folding
portion of the exterior minor assembly. In further aspects, the security
light includes a housing, a light source positioned to the housing, a
light reflecting member supported in the housing, and a cover. The light
reflecting member directs light from the light source through the cover.
Preferably, the housing is substantially positioned in the non-folding
portion of the exterior mirror assembly. Furthermore, the cover is
preferably substantially flush with an outer surface of the non-folding
portion to reduce the aerodynamic drag of the security light.

[0020] It can be appreciated from the foregoing that the exterior mirror
system of the present invention permits an approaching vehicle to observe
an actuated signal light without the interference from headlights or
brake lights. The exterior minor system may include a unitary module,
which is easily installed or removed for repair, or a signal light
assembly which is incorporated into the housing of the mirror assembly.

[0021] These and other objects, advantages, purposes and features in the
invention, will become more apparent from the study of the following
description taken in conjunction with the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0063] Referring now specifically to the drawings, and the illustrative
embodiments depicted therein, a vehicle personal security lighting system
25 includes an exterior mirror assembly 26 having a conventional
reflectance element 28, a security light 30, preferably white, or clear,
and a signal light 32, preferably red, incorporated in a housing, or
casing, 34. Casing 34 is connected by a neck 36 to a stationary panel or
sail 38 adapted for incorporation with the forward portion of the vehicle
side window assembly, and which mounts mirror assembly 26 to the door of
a vehicle 40 (see FIG. 10). Reflectance element 28 may be any of several
reflectors, such as glass coated on its first or second surface with a'
suitable reflective layer or layers, such as those disclosed in U.S. Pat.
No. 5,179,471, the disclosure of which is hereby incorporated by
reference herein, or an electro-optic cell including a liquid crystal,
electrochromic, or electrochemichromic fluid, gel or solid-state compound
for varying the reflectivity of the mirror in response to electrical
voltage applied there across as disclosed in U.S. Pat. No. 5,151,824, the
disclosure of which is hereby incorporated by reference herein.

[0064] With reference to FIGS. 7 and 8, as is conventional, reflectance
element 28 is mounted to a bracket 43 by an actuator 42. Casing 34 is
mounted to bracket 43. Actuator 42 provides remote positioning of
reflectance element 28 on two orthogonal axes. Such actuators are well
known in the art and may include a jackscrew-type actuator 42 such as
Model No. 1116-49-8001 (right-hand mirror) and Model No. 1116-49-8051
(left-hand mirror) by Matsuyama of Kawagoe City, Japan, as illustrated in
FIG. 7, or a planetary-gear actuator 42' such as Model No. 540 (U.S. Pat.
No. 4,281,899) sold by Industrie Koot BV (IKU) of Montfoort, Netherlands,
as illustrated in FIG. 20. As is also conventional, the entire casing 34
including actuator 42, 42' is mounted via bracket 43 for breakaway motion
with respect to stationary panel 38 by a breakaway joint assembly 44.
Breakaway joint assembly 44 (FIG. 9) includes a stationary member 46
attached to vehicle 40, a pivoting member 48 to which bracket 43 and
casing 34 are attached, and a wire-way 50 through which a wire cable 52
passes. Wire cable 52 includes individual wires to supply control signals
to actuator 42, 42', as well as signals to control the level of
reflectivity, if reflective element 28 is of the variable reflectivity
type noted above, such as an electrochromic mirror. Power may also be
supplied through cable 52 for a heater (not shown) as disclosed in U.S.
Pat. No. 5,151,824 in order to evaporate ice and dew from reflective
element 28.

[0065] With reference to FIG. 5, actuator 42, 42' receives a first set of
reversible voltage signals from a switch 54, in order to bidirectionally
pivot in one axis, and a second set of reversible signals from a switch
56, in order to bidirectionally pivot in the opposite axis, as is
conventional. Switches 54 and 56 are actuated by a common actuator (not
shown) that is linked so that only one of the switches 54 and 56 may be
actuated at a time. In this manner, actuator 42, 42' may utilize one
common conductor for both switches 54, 56.

[0066] Each of the security light 30 and signal light 32 includes a light
source 60 and reflector 62 behind a lens 64 (FIG. 8). Light source 60,
reflector 62 and lens 64 are designed for security light 30 to project a
pattern 66 of light, such as white light, through a clear, non-filtering
lens, in order to establish a security zone around the vehicle (FIGS.
10-12). Pattern 66 extends rearward from mirror assembly 26. Vertically,
pattern 66 contacts the ground at 68 in the vicinity of entry and exit by
the vehicle occupants (FIGS. 10 and 12). Laterally, pattern 66 fans out
into contact with the side 70a, 70b of the vehicle. This contact washes
the sides of the vehicle to reflect the light in order to further
illuminate the area in order to establish the security lighting zone
(FIGS. 11 and 12). In a preferred embodiment, pattern 66 extends
rearwardly from mirror assembly 26 without projecting any portion of the
pattern forwardly of the mirror assembly.

[0067] Signal light 32 generates a light pattern 72, which is directed
generally horizontally rearwardly of vehicle 40 (FIGS. 13-15). Pattern 72
is laterally directed substantially away from side 70a, 70b of vehicle 40
so that the driver of vehicle 40 does not directly intercept pattern 72,
although a minor intensity (such as 10%) of the pattern is intercepted by
the driver in order to provide awareness of the actuating of the signal
light. Pattern 72 fans laterally away from side 70a, 70b to an extent
that is parallel the face of reflectance element 28, which is
substantially perpendicular to side 70a, 70b (FIG. 14). Thus, the driver
of another vehicle (not shown) passing vehicle 40 on the left or right
side of vehicle 40 will intercept pattern 72 while the vehicle is behind
and beside vehicle 40. Although, in an illustrated embodiment, lens 64 of
signal light 32 is substantially planar, lens 64 of signal light 32 could
be made to wrap around the outward side of casing 34 in order to function
as a side marker for the vehicle as is required in some European
countries.

[0068] Vehicle mirror assembly security system 25 is actuated by a control
system 74 (FIG. 5). Control system 74 includes means for actuating
security light 30 including a remote transmitting device 76 and a
stationary receiving device 78. Transmitting device 76 may be remotely
carried by the vehicle operator and includes switches 80 and 81 in order
to actuate the transmitting circuitry to transmit a signal form antenna
82, which is received by antenna 84 of receiving device 78. Receiving
device 78 is mounted in the vehicle, such as in the vehicle trunk
compartment, and includes an output 86 in order to operate remote door
lock circuit 88, as is conventional. Output 86 is, additionally, provided
as an input 90 of a lockout circuit 92, whose output 94 is supplied to
security lamp 30. Input 90 may additionally be actuated by a timeout
circuit 96, which is conventionally supplied in a vehicle in order to dim
the interior lights, following a slight delay, after the occurrence of an
event, such as the opening and closing of the doors of the vehicle.
Signal light 32 is actuated on line 98 from either a' turn indicator
circuit 100 or a stop lamp indicator circuit 102, both of which are
conventionally supplied with vehicle 40.

[0069] In operation, when the operator actuates switch 80 of transmitting
device 76, receiving device 78 produces a signal on output 86 in order to
cause remote door lock circuit 88 to unlock the doors. Alternatively,
actuation of switch 81 on remote transmitting device 76 causes receiving
device 78 to produce a signal on output 86 to cause remote door lock
circuit 88 to lock the vehicle doors. The signal on output 86 actuates
security lamp 30 provided that lockout circuit 92 does not inhibit the
signal. Lockout circuit 92 responds to operation of the vehicle in order
to avoid actuation of security lamp 30 when the vehicle is in motion.
Such lockout circuits are conventional and may be responsive to placing
of the vehicle transmission in gear of sensing of the speed of the
vehicle, or the like. Security lamp 30 is also actuated, in response to
interior lighting device timeout circuit 96, whenever the interior lights
of the vehicle are being actuated by timeout circuit 96, provided that
lookout circuit 92 does not inhibit the signal from security lamp 30.
This is provided in order to allow security lamp 30 to be actuated in
response to the entry to, or exit from, vehicle 40 without the operator
utilizing transmitting device 76 to lock or unlock the doors. Signal lamp
32 is actuated in response to turn indicator circuit 100 whenever the
operator moves the indicator stick in the direction of that particular
signal lamp 32. Signal lamp 32 may additionally be actuated from stop
lamp circuit 102 in response to the driver actuating the vehicle's
brakes.

[0070] In the embodiment illustrated in FIGS. 1 and 5, lens 64 of signal
lamp 32 is adapted to filter the light provided from lamp 32 so as to be
red and is provided for vehicles 40 in which the stop lamps and rear turn
indicator lamps are, likewise, red. Because signal lamp 32 shines red,
pattern 72 is restricted from extending forward of the vehicle. This is
in order to comply with regulations prohibiting red lights from causing
confusion with emergency vehicles by shining forward of the vehicle.

[0071] For vehicles having red stoplights and amber turn indicators in the
rear, a vehicle mirror security assembly 25' includes an exterior mirror
assembly 26' and a control system 74' (FIGS. 4 and 6). Exterior mirror
assembly 26' includes a security light 30', preferably white or clear,
and a pair of signal lights 32a' and 32b'. Signal light 32a' is amber and
is actuated directly from turn indicator circuit 100', This amber color
can be provided either by an amber light bulb or source, or a filtering
lens providing an amber color. Signal light 32b' is red and is actuated
directly from stop lamp circuit 102'. Each of the light patterns
generated by signal lights 32a' and 32b' substantially correspond with
light pattern 72. The light pattern generated by security light 30' is
substantially equivalent to pattern 66. With the exception that turn
signal indicator circuit 100' actuates signal light 32a' and stop lamp
circuit 102' actuates signal light 32b', control system 74' operates
substantially identically with control circuit 74.

[0072] In the illustrated embodiment, light source 60, for both security
light 30 and signal light 32, may be supplied as a conventional
incandescent or halogen lamp 60a (FIG. 7). Alternatively, a conventional
incandescent fuse lamp 60b may be used (FIG. 16). Alternatively, a vacuum
fluorescent lamp 60c, which is available in various colors, may be used
(FIG. 17). Alternatively, a light emitting diode 60d may be used (FIG.
18). As yet a further alternative, a fiber optic bundle 104 forming a
light pipe may be positioned to discharge light behind lens 64. Fiber
optic bundle 104 passes through breakaway joint 44 in wire-way 50 in
order to transmit light from a source (not shown) within vehicle 40. By
way of example, lens 64 may be supplied as a segmented lens, a prismatic
lens, or a Fresnel lens in order to generate light patterns 66 and 72.
Bracket 43 and breakaway joint 44 are marketed by Donnelly Corporation,
the present assignee, of Holland, Mich. The remote actuator composed of
remote transmitting device 76 and stationary receiving device 78 may be
radio frequency coupled, as is conventional. Alternatively, they may be
infrared coupled as illustrated in U.S. Pat. No. 4,258,352.

[0073] Although the invention is illustrated in a mirror assembly
utilizing an automatic remote actuator, it may also be applied to manual
remote actuators and handset actuators. As previously set forth,
reflectance element 28 may be conventional or may be supplied as an
electrochromic self-dimming mirror. Although the invention is illustrated
with breakaway joint 44, the invention may also be applied to mirrors
that are rigidly mounted to the vehicle.

[0074] Referring to FIGS. 21-23, the numeral 210 generally designates a
driver's side exterior mirror assembly of the present invention, with the
numeral 210' generally designating a passenger's side exterior mirror
assembly of the present invention which is preferably a mirror image of
driver's side exterior mirror assembly 210. Exterior rearview mirror
assembly 210 includes a mirror casing or housing 212, which includes a
sail 213 that is adapted to mount on a vehicle, a reflective element 214,
which is supported in casing 212, and a signal light 216 which is also
supported in casing 212. Signal light 216 is adapted to direct light into
the blind spot of the driver and, preferably, provides a light forwardly
and rearwardly of the vehicle so that vehicles approaching the vehicle
may observe the signal light. Additionally, signal light 216 is adapted
to project light laterally with respect to the vehicle to provide a side
light and so function as a side marker. Furthermore, it should be
understood that light pattern 217 is generally cone shaped and may
project above and below the horizontal plane extending through mirror
assembly 210 similar to the illustration in FIG. 15 and preferably
projects light above and below the horizontal plane by in a range of
about 5° to about 25° and, more preferably, about
15°. As will be more fully described, signal light 216 is
preferably adapted to direct the light in a light pattern 217 (with
passenger side exterior rearview mirror assembly 210' having a mirror
image light pattern 217'), such that the light does not extend into the
cabin of the vehicle to distract the driver of the vehicle. Furthermore,
by projecting light rearwardly, forwardly, and to the side of the
vehicle, approaching vehicles, whether from the forward direction of the
vehicle or from the rearward direction of the vehicle or vehicles that
are entering the blind spot of the vehicle, can observe the signal light
and have advanced notice that the driver of the vehicle intends to make a
lane change or turn.

[0075] Rearview mirror assembly 210 may comprise a fixed position exterior
rearview mirror assembly or may comprise a break-away rearview mirror
assembly, which moves between a normal operating position, in which the
rearview mirror assembly is extended from the vehicle, to a folded
position against the body of the vehicle when the exterior rearview
mirror assembly 210 is impacted with sufficient force. Reference is made
to the previous embodiment, exterior mirror assembly 26, for one example
of a break-away rearview mirror assembly.

[0076] Casing 212 is cup shaped and includes a rearwardly facing opening
212a in which reflective element 214 is supported. Casing 212 is
preferably injection molded from a suitable plastic, such as nylon,
acrylonitrile butadiene styrene (ABS) or suitable resinous plastic, or
the like, which is commercially available under the trademark TERLURAN
KR2889®, by BASF Company of Wyandotte, Mich. Alternately, other
resinous, melt processible plastics or moldable materials such as
mineral-filled or glass filled nylon or polyester and polypropylene could
be used to form case 212. A suitable nylon is 13% glass modified nylon
6:6 sold as ZYTEL 71G13L® by I.E. DuPont de Nemours & Company of
Wilmington, Del., or PA123G13BK-47 by Bay Resins Inc. of Millington, Md.
A suitable polypropylene is TENITE P6M4Z-007® by Eastman Chemical
Products, Inc., Kingsport, Tenn. Alternately, casing 212 may comprise a
fiber reinforced nylon plastic, thermoplastic, or polypropylene or other
similar thermoplastic or thermoset materials.

[0077] As described above, reflective element 214 is supported in casing
212. As best seen in FIG. 24, reflective element 214 is mounted to a
backing plate 214a which is supported by a positioning device, such as an
actuator 218, which provides adjustment for reflective element 214.
Actuator 218 is supported on a mounting bracket 220, which in turn is
secured to casing 212 on mounting bosses 222 provided on casing wall 224.
In the illustrated embodiment, actuator 218 comprises an electrical
actuator, which pivots reflective element 214 in casing 212. Preferably,
actuator 218 comprises dual axis positioning device that permits
adjustment of the position of the reflective element 214 and backing
plate 214a about both vertical and horizontal axes as is known in the
art. It should be understood, however, other positioning devices may be
used including manually operated actuators, a remote manually operated
actuators, such as a BODEN cable actuator, or the like.

[0078] Reflective mirror element 214 may comprise a conventional
non-electro optic planar or convex mirror element including a metallic
reflector coated glass substrate, such as with a thin chromium or
chromium alloy reflector coating, or a non-metallic reflector layer, such
as a dichroic layer as described in U.S. Pat. No. 5,207,492 to Roberts et
al. or a reflector comprising a silicon reflective layer such as
described in U.S. Pat. No. 5,535,056 to Caskey et al., which are herein
incorporated by reference in their entireties. Alternatively, reflective
element 214 may comprise a variable reflective electro optic element,
such as electrochromic mirror element comprising one of several types of
electrochromic elements, for example an element of the
electrochemichromic type, which is disclosed in U.S. Pat. No. 5,140,455
issued to Varaprasad et al., or may be of the solid state type such as
disclosed in U.S. Pat. No. 4,712,879 issued to Niall R. Lynam et al.,
U.S. patent application Ser. No. 08/023,675, filed Feb. 22, 1993, by
Varaprasad et al., U.S. patent application Ser. No. 08/913,557, filed
Feb. 8, 1994, by Varaprasad et al., and U.S. patent application Ser. No.
08/238,521, filed Mar. 5, 1994, by Varaprasad et al., now U.S. Pat. No.
5,668,663, all commonly assigned with the present application to Donnelly
Corporation of Holland, Mich., the disclosures of which are herein
incorporated by reference in their entireties. Such electrochromic
elements comprise an electrically responsive electrochromic medium that
modulates reflectivity from a reflective element. Such electrochromic
mirror elements are continuously variable and exhibit multiple reflectant
states as the voltage applied thereto is varied. Alternately, reflective
element 214 may comprise other electro optic mirror elements such as a
liquid crystal mirror and the like. Where reflective element 214
comprises an electrochromic mirror element, the electrochromic mirror
element is preferably driven by signals produced by a variable reflectant
system of the type disclosed in U.S. patent application Ser. No.
08/316,047 for a "Modular Variable Reflectant Mirror Assembly", filed
Sep. 30, 1994, by Kenneth L. Schierbeek et al., now U.S. Pat. No.
5,659,423 which is herein incorporated by reference in its entirety.

[0079] It should be understood, although not described herein, that one or
more electrical or electronic components may be mounted in casing 212,
such as the interface transaction system described in U.S. patent
application entitled A VEHICLE MOUNTED REMOTE TRANSACTION INTERFACE
SYSTEM filed by Martin DeVries and Niall R. Lynam on Apr. 8, 1998, Ser.
No. 09/057,428, now U.S. Pat. No. 6,158,655, and/or an electronic module,
which may include one or more electrical or electronic devices, such as
antennas and circuitry for rain sensors, heating elements, and the like,
as described in pending U.S. patent application entitled MODULAR REARVIEW
MIRROR ASSEMBLY INCLUDING ELECTRONIC MODULE, Ser. No. 08/702,228 which
was filed Aug. 23, 1996, by Niall Lynam et al., now U.S. Pat. No.
6,019,475, and which are commonly assigned to Donnelly Corporation of
Holland, Mich., the disclosures of which are incorporated by reference
herein in their entireties.

[0080] As best seen in FIGS. 22 and 26, signal light 216 is positioned in
a lower portion or bottom rim of casing 212 and includes a light
conduiting member or light pipe 230 and a light source 232. The color of
the light emitted from signal light 216 is preferably amber,
yellow-amber, or amber-red, depending on its application and may be
generated by a boot or cover, a filter, a reflector which surrounds the
light source, the light source or the light pipe or a combination of one
or more of the aforementioned devices. For example, light source 232 may
produce, for example an amber light from a coating on the light source
bulb or from a gas enclosed in the bulb or from the light producing
element of the light source. In addition, signal light 216 preferably
produces a light intensity of at least about 0.3 and in the range of
about 0.3 to about 200 candela, more preferably, in a range of about 0.6
to about 150 candela, and most preferably, in a range of about 1.0
candela to about 25 candela, such that signal light 216 preferably meets
the specification for the applicable automobile industry standards such
as Japanese Industrial Standard (JIS) 5500; ECE Reg. 48; EEC No. 76/759;
and/or E/ECE/324 Reg. No. 6. Moreover, signal light 216 may produce a
variable light pattern intensity. For example, referring to FIG. 21, in
the region 217c of light pattern 217 which is forward of transverse axis
211b, the light intensity may have one intensity value, while the region
217d rearward of transverse axis 211b may include another light intensity
value. Furthermore, each region 217c or 217d may have a variable
intensity pattern. For example, the portion of the region 217c or 217d
nearest to axis 211b may have a higher light intensity than portions of
the region 217c or 217d angled further away from axis 211b. In this
manner, signal light 216 is visible to persons on the road who are
approaching the vehicle from the forward or rearward direction or persons
located adjacent the vehicle.

[0081] Light pipe 230 is preferably formed, such as by molding, from a
plastic, such as polycarbonate, acrylic or the like, and is, therefore,
substantially rigid. Alternately, light pipe 230 may comprise a flexible
bundle of individual fibers or an individual flexible fiber. Furthermore,
light pipe 230 is adapted to transmit or direct light from light source
232 along a longitudinal axis 230a of light pipe 230 and reflect the
light from light source 232 as it extends through the light pipe in
directions generally lateral to the longitudinal axis 230a of light pipe
230, as will be more fully described below.

[0082] Referring to FIG. 26, light pipe 230 includes a first side 234,
which provides a light emitting surface and is substantially planar, and
an opposed side 236 which includes a plurality of faceted surfaces 238.
Faceted surfaces 238 provide internal light reflecting surfaces and have
a stepped configuration, with the cross-section of light pipe 230 being
incrementally reduced from a first end or approximate end 240 to a second
end or distal end 242. Light pipe 230 is preferably positioned in casing
212 such that first end 240 is positioned closer to the vehicle than
second end 242 and such that first side 234 is oriented facing outwardly
from casing 212. Moreover, light pipe 230 is preferably positioned in
casing 212 with minimal protrusion into the slipstream of the mirror
assembly so as to reduce the aerodynamic drag and, most preferably, with
first side 234 substantially flush with the outer surface of the lower
portion or bottom rim of casing 212. First end 240 is substantially
planar and generally orthogonal to first side 234 and defines a light
input surface 244. Light source 232 is positioned adjacent light input
surface 244 and preferably in substantially close proximity to light
input surface 244 so that a high percentage, if not all, light emitted
from light source 232 is directed into light pipe 230. Optionally, light
source 232 may be optically coupled to light input surface 244 by, for
example, an optical adhesive.

[0083] As described above, first side 234 of light pipe 230 provides light
emitting surface 245, through which light from light source 232 is
emitted. Again referring to FIG. 26, when light enters light pipe 230
through light input surface 244, the light rays are internally reflected
off faceted surfaces 238 and, some of which, are internally reflected off
planar surface 234a of first side 234 so that the light from light source
232 is directed laterally through first side 234 and through light
emitting surface 245 in directions which are angled with respect to first
side 234. In preferred form, the light pattern emitted light pipe 230
includes a plurality of light regions which are angled away from the side
of the vehicle to restrict the light from entering into the vehicle. In
this manner, light pipe 230 transmits or conduits the light from light
source 232. It should be understood that the geometry of light pipe 230
permits light pipe 230 to direct light in a manner that relies on
internal reflections within light pipe 230; therefore, no reflective
coatings are necessary. Consequently, light pipe 230 is easier and less
costly to manufacture. However, it can be appreciated that faceted
surfaces 238 may include reflective coatings, such as formed by vacuum
metalizing.

[0084] As best seen in FIG. 24, light pipe 230 is mounted between a lower
or bottom wall portion 224a of casing wall 224 and a flange 246 which
extends from a back wall portion 224b of casing wall 224. Similarly,
light source 232 is supported between flange 246 and lower portion 224a
of casing wall 224 and is positioned adjacent first end 240 of light pipe
230, as described above. It should be understood from the foregoing, that
reflective element 214 is independently mounted from light pipe 230 and,
therefore, can move independently from light pipe 230, which is
preferably mounted in a fixed position in casing 212.

[0085] Optionally, signal light 216 includes a second light pipe 250.
Light pipe 250 is a similar construction to light pipe 230, except that
light pipe 250 includes a curved outer surface 252 which follows the
curvature of casing 212 as shown in FIGS. 23 and 24 and which defines a
light emitting surface. Light pipe 250 includes a first or approximate
end 254, which provides a light input surface, and a second or distal end
256. As best seen in FIG. 23, light pipe 250 wraps around casing 212 to
permit light to be reflected generally laterally from exterior rearview
assembly 210 to provide a side signal or side marker to cars which are
positioned in the blind spot of the vehicle. A second light source 258 is
positioned adjacent first end 254 so that light which is emitted from
light source 258 is directed along the longitudinal axis 250a of light
pipe 250 and laterally with respect to longitudinal axis 250a in a
similar manner to light pipe 230.

[0086] Preferably, light pipes 230 and 250 direct light in light pattern
217, shown in FIG. 21. Light pattern 217 is defined between leading edges
217a and 217b, wherein leading edge 217a forms an angle α with
respect to the vehicle axis 211a of vehicle 211, as measured in a counter
clock-wise direction, and leading edge 217b forms an angle β with
respect to vehicle axis 211a as measured in a clock-wise direction. These
angles vary depending upon the applicable guidelines or specifications of
the country in which the vehicle is sold. For example, α may be in
a range of about 0° to about 45°. β may be in a range
of about 0° to about 15°. In some countries, a may be in a
range of about 0° to about 40°, and β may be in a
range of about 0° to about 5°.

[0087] Light sources 232 and 258 are preferably energized by power lines
260 which extend through flange 246 so that they can be bundled along
with other power or communication lines which extend from exterior mirror
casing 212 to the interior of the vehicle to couple light sources 232 and
258 to the electrical system of the vehicle. Light sources 232 and 258
may comprise a laser diode, a solid state emitter such as a light
emitting diode, an incandescent light source, a fluorescent light source,
such as a cold cathode fluorescent light, a phosphorous lamp, a neon
light, a discharge lamp, an arc lamp, and an electro-luminescent light,
including inorganic or organic electro-luminescent sources.

[0088] Optionally, two or more of such light sources may be incorporated
into exterior mirror assembly 210 for directing light into the respective
light input surfaces 244 and 256 of light pipes 230 and 250,
respectively. Furthermore, a plurality of light emitting sources may be
grouped to provide a more intense illumination. As described above, a
variety of emitting sources may be used as light emitting sources 232 and
258, including but not limited to a very high intensity amber and
reddish-orange light emitting diode (LED) sources, such as solid state
light emitting diode sources utilizing double hetero junction AlGaAs/GaAs
Material Technology, such as very high intensity LED lamp T-1% (5 mm)
HLMT-4100/4101, available from Hewlett Packard Corporation, Palo Alto,
Calif., for which used transparent substrate aluminum indium gallium
phosphide (AlInGaB) Material Technology, commercially available from
Hewlett Packard Corporation under the designation T-13/4 (5 mm)
HLMT-DL00, HLMT-CH00, HLMT-CL00, HLMT-CH15, HLMT-DH00 or which use
InGaAlB Material Technology available from Toshiba Corporation of
Laythem, N.Y. such as under the designation TLRH180D. Light emittance
colors provided by such solid state sources include orange, yellow,
amber, and reddish-orange, preferably without the need for ancillary
filters. The preferred solid state light emitting diodes operate at
25° C., or thereabouts, and operate with a forward voltage of
about 2 volts to about 5 volts; have a luminance intensity (measured at
peak of the spacial radiation pattern which may not be aligned with a
mechanical access of the source package) of a minimum at 20 mA current of
about 500 to about 5,000 lcd (typically about 700 to about 7,000 mcd);
operated at a forward current of about 20 mA to about 50 mA; emit with a
dominant wave length (CIE Chromaticity diagram) of about 530 inn to about
60 nm; and have a viewing angle to θ1/2, where θ1/2 is the
off axis angle where the luminance intensity is 1/2 the peak intensity of
about 5° to about 25°.

[0089] Alternately, vacuum fluorescent sources such as 12-volt battery
driven high luminescent vacuum fluorescent sources may be used. It may
also be advantageous to use sources which operate efficiently at about 12
volts or lower since these voltages are particularly suited to
conventional motor vehicle electrical systems. Also, ultra high
luminescent vacuum fluorescent sources such as those suitable for head
set display applications in motor vehicles may be used with appropriate
circuitry.

[0090] Alternately, non-LED non-incandescent light emitting sources can be
used such as electro-luminescent sources or semiconductor laser sources.
Electro-luminescent sources may be either inorganic or organic
electro-luminescent sources. Light emitting sources 232 and 258,
preferably have well defined light patterns, such as a cone of directed
light which eliminates the need for reflectors or other separate optical
components that direct the light where desired. In addition, light
emitting sources 232 and 258 are preferably mounted on or within mirror
casing 212 as described previously. Alternately, light sources 232 and
258 may be in the form of a light pipe which directs light from a remote
light source located in the vehicle. Such a light pipe may comprise, for
example a flexible light pipe such as a fiber optic cable. In which case,
the distal end of the fiber optic cable is positioned adjacent the
respective light input surfaces 244 and 256 of light pipes 230 and 250.

[0091] In the event that the light emitting source comprises a light
emitting diode, a resistor is preferably connected in series with a
respective light emitting diode to act as a voltage divider so as to
reduce the ignition voltage of the vehicle, which is in the range of 9-16
volts (normally 12 volts), for the desired operating voltage of the light
emitting diode, which is typically on the order of about one volt to
about five volts. Each resistor preferably has a resistance of less than
about 1,500 ohms and greater than about 100 ohms, more preferably, less
than about 1,000 ohms and greater than about 200 ohms.

[0092] Although illustrated herein as being located along the bottom rim
of the exterior trim housing, other locations are possible for the signal
light of the invention, including the top and outboard rim of the
exterior housing, and even elsewhere on the exterior vehicle body as
appropriate.

[0093] Referring to FIGS. 27-29, a second embodiment 310 of the exterior
rearview mirror assembly of the present invention is illustrated.
Exterior rearview mirror assembly 310 includes a housing or casing 312 in
which a reflective element 314 is supported. In addition, exterior
rearview mirror assembly 310 includes a signal light and, preferably, a
signal light 316 which provides a light pattern similar to light pattern
217 described in reference to the first embodiment and is supported by
casing 312 which will be further described below.

[0094] Reflective element 314 is mounted to a backing plate 314a, which is
supported on a positioning device or actuator 318, which in turn is
mounted to a mounting bracket 320. In the illustrated embodiment,
mounting bracket 320 is supported by mounting bosses 322 provided on
casing wall 324 of casing 312. It should be understood, that reflective
element 314, therefore, can move independently of the signal light 316,
which is preferably mounted in a fixed position relative to casing 312.
However, other mounting arrangement may be used for reflective element
314 and for the exterior rearview assembly, including a fixed position
exterior rearview mirror assembly or a mounting arrangement in which
mounting bracket is rotatably coupled to a vehicle mounting bracket to
provide a break-away function of the exterior rearview mirror assembly.
In a break-away exterior mirror assembly, signal light 316 is preferably
mounted to move with the casing and, therefore, remains fixed relative to
the casing.

[0095] As best seen in FIG. 27, signal light 316 is mounted to a bottom
wall portion 326 of casing wall 324. Bottom wall portion 326 of casing
wall 324 includes a stop or an abutment 328 against which signal light
316 abuts when mounted to casing 312. Signal light 316 is preferably
mounted to casing 312 by for example fasteners, such as threaded
fasteners, keys, or projecting pins with enlarged heads which provide a
snap-fit coupling between signal light 316 and bottom wall 326.
Alternately, signal light 316 may include tracks or guides and with
casing 312 including a corresponding guide or track so that signal light
316 can be inserted between the respective guides, or tracks.
Furthermore, signal light 316 includes a lower most surface 316a which
preferably aligns and, more preferably, is flush with the lower most
surface 328a of stop 328 so that when installed, signal light 316 follows
the aerodynamic contours of casing 312 to provide an aerodynamically
contoured exterior rearview mirror assembly 310.

[0096] Referring to FIGS. 28 and 29, signal light 316 includes a housing
330 which includes a cover 331 and a base 332. Base 332 includes a
mounting portion and a raised or projecting portion 333 which defines a
mounting surface 334. Housing 330 is preferably plastic, such as nylon, a
melt processible plastic, including for example polycarbonate, acrylic,
or the like and, additionally, matches the color of casing 312. Cover
331, which is preferably a clear plastic cover, extends over base 332 and
is secured thereto using conventional means, including for example
releasable couplers, including threaded fasteners, snap-fit couplers or
the like, or by welding, such as sonic welding, heat staking or the like,
or by an adhesive. Cover 331 defines a cavity or space 332a between base
332 and cover 331. Base 332 supports a light source 342, which is housed
in cavity 332a, and a light reflecting member 335 which is preferably
mounted to mounting surface 334 for reflecting light from light source
342 outwardly from signal light 316. Light reflecting member 335
preferably comprises a multi-faceted reflector having a compound shape
and includes a plurality of reflector elements 336, 338, and 340. Each
reflector elements 336, 338, and 340 may comprise a metal reflector, such
as a stamped aluminum reflector, a polished metal reflector, a
painted/coated printed surface with a high specular and/or diffused
paint, film, tape, coating, or the like, a vacuum metalized substrate,
such as vacuum metalized glass or plastic, a metalized or reflective
mineral filled substrate, such as a mineral filled plastic substrate, a
reflective metal filled substrate, such as a metal filled plastic, or the
like. Each of the respective reflective elements 336, 338, and 340 may
have a concave, a convex, or planar surface, or a multiradius surface
such as an anamorphic asphere shape.

[0097] Preferably light source 342 is positioned adjacent reflector
element 336 and sufficiently spaced from reflector element 336 such that
the light emitted from light source 342 reflects off reflector elements
336, 338, and 440 to provide a pattern as shown in FIG. 28. Light source
342 may comprise a bulb, a diode, or the like, and is powered through
wiring 343 which extends from signal light 316 to casing 312, for example
by way of an opening 330a provided in base portion 332 of housing 330.
Optionally, light source 342 may comprise a light pipe (not shown) which
delivers or directs light from a remote light source in the vehicle in a
similar manner as described in reference to the previous embodiment.

[0098] As described above, cover 331 may be integrally molded with base
portion 332. In this manner, light source 342 may be inserted into cavity
332a through opening 330a of base 332. Furthermore, cavity 332a may be
reduced such that cavity 332a comprises a light source receiving socket.
In addition, signal light 316 may include a light conduiting member, such
as described in reference to signal light 216 or signal light 416,
positioned in cavity or space 332a to further enhance the direction of
light emitted from light source 342.

[0099] Referring to FIG. 28, signal light 316 emits light in a light
pattern 344, which is defined between leading edges 346 and 348. When
mounted to casing 312, light pattern 344 directs light forwardly and
rearwardly of the vehicle and to the side of the vehicle but away from
the cabin of the vehicle so as to avoid contact with the driver's eyes
similar to light pattern 217 in FIG. 21.

[0100] As best seen in FIG. 27, cover or lens 331 extends over housing 330
from a first end or approximate end 352 to a second or distal end 354.
For further details of light source 342, reference is made to the
description of light sources 232 and 258 as described in reference to the
first embodiment. Preferably, cover 331 includes a neutral spectra
content and comprises a plastic lens, such as a polycarbonate lens.
Furthermore, cover 331 may be a prescription lens such as, a fresnel
lens, including a micro fresnel lens, a diffusive optic lens, a
diffractive optic lens, a refractive optic lens, a reflective optic lens,
a holographic optic lens, a binary optic lens, a clear optic lens, a
prismatic lens, a pillow lens, and a sinusoidal optic lens, or the like.
In which case, the color of the light from signal light 316 may be
introduced by light source 342, a boot or cover over light source 342, a
filter, or reflector 335. Similar to as described in reference to light
sources 232 and 258, signal light 316 may emit an amber, yellow-amber, or
red-amber light. Furthermore, cover 331 may optionally blend with the
color of casing 312, with signal light 316 still emitting an amber,
amber-yellow or red-amber light. Alternately, the color of the light may
be generated by cover 331 or a combination of any one or more of the
aforementioned devices.

[0101] Preferably, signal light 316 produces a light intensity in the
range of about 0.3 to about 200 candela, more preferably, in a range of
about 0.6 to about 150 candela, and most preferably, in a range of about
1.0 to about 100 candela, such that signal light 316 preferably meets the
applicable specifications for the automobile industry, as described in
the previous embodiment. In this manner, signal light 316 is visible to
persons on the road who are oncoming or approaching the vehicle from the
rearward direction. Furthermore, signal light 316 preferably extends to
the outer most portion and wraps around the bottom wall 326 of casing 312
so that light emitted from signal light 316 is visible from the side of
the vehicle, and vehicles which are in the vehicle's blind spot can
clearly see the signal light when actuated.

[0102] Preferably, signal light 316 is a unitary module or modular turn
signal which can be easily serviced and/or replaced in its entirety.
Furthermore, signal light 316 is preferably at least substantially water
impervious and optionally may include a socket or electrical connection
to the vehicle electrical wiring system. In addition, as described in
reference to the previous embodiment, signal light 316 may incorporate a
circuit board for flexible circuitry, which couples to the electrical
system of the vehicle for powering light source 342.

[0103] Referring to FIGS. 30-31, the numeral 410 designates a third
embodiment of the exterior rearview assembly of the present invention.
Exterior rearview assembly 410 includes a mirror casing or housing 412,
which includes a sail 413 which is adapted to mount on a vehicle, a
reflective element 414 which is supported in housing 412, and a signal
light 416 which is also supported in housing 412. Signal light 416 is
adapted to direct light forwardly and rearwardly of the vehicle so that
vehicles approaching from the opposite direction of the vehicle and
rearwardly of the vehicle may observe signal light 416. Additionally,
signal light 416 is adapted to project light laterally with respect to
the vehicle to provide a side light and so function as a side marker.
Similar to exterior mirror assembly 210, signal light 416 is preferably
adapted to direct the signal light in a light pattern 417 such that the
light does not extend into the cabin of the vehicle to distract the
driver of the vehicle. Furthermore, by projecting light rearwardly,
forwardly and laterally from the side of the vehicle, approaching
vehicles, whether from the forward direction of the vehicle or from the
rearward direction of the vehicle or vehicles that are entering the blind
spot of the vehicle, can observe the signal light and have advanced
notice if the driver of the vehicle intends to make a lane change or
turn.

[0104] Rearview mirror assembly 410 may comprise a fixed position exterior
rearview mirror assembly or may comprise a break-away rearview mirror
assembly, which moves between normal operating position in which the
rearview mirror assembly is extended from the vehicle to a folded
position against the body of the vehicle and the exterior rearview mirror
assembly 410 is impacted with sufficient force. Examples of break-away
rearview mirror assemblies are well known and reference is made to the
first embodiment of the exterior rearview mirror assembly for at least
one example such a break-away assembly.

[0105] Housing 412 is generally cup-shaped and includes a rearwardly
facing opening 412a in which reflective element 414 is supported.
Reference is made to exterior rearview mirror assembly 210 for examples
of preferred material for housing 412. As described above, reflective
element 414 is supported in housing 412. Preferably, reflective element
414 is mounted on a backing plate 414a, which in turn is supported by a
positioning device, for example an electrical actuator or the like.
Again, reference is made to the exterior rearview mirror assembly 210 for
an example of how reflective element 414 is supported in housing 412.
Furthermore, reference is made to exterior rearview mirror assembly 210
for examples of preferred reflective elements and for examples of other
components which may be mounted or housed in exterior rearview mirror
assembly 410.

[0106] As best seen in FIGS. 30 and 31, signal light 416 is preferably
positioned in a lower portion or bottom rim of casing 412 and includes a
light conduiting member or light pipe 430 and a plurality of light
sources 432. As described in reference to the previous embodiments, the
light emitted from the signal light 416 is preferably yellow, amber,
yellow-amber, or amber-red depending on its application. Again, reference
is made to the earlier embodiments for examples of how the color is
generated. Light pipe 430 is preferably formed, such as by molding, from
a plastic material, such as polycarbonate or acrylic or the like, and is,
therefore, substantially rigid. As best seen in FIG. 31, light pipe 430
includes a plurality of light transmitting or conduiting portions 430a,
which are spaced and arranged in a generally radial fashion. Each light
transmitting or conduiting portion 430a includes a leading edge 434,
which defines a light input surface. Furthermore, each light transmitting
or conduiting portion 430a includes a distal surface or outboard edge 436
which defines a light emitting surface which is preferably arranged or
formed, to follow the contour of exterior mirror housing 412. In
addition, each light transmitting or conduiting portion 430a includes
side walls 438 and 440, which extend from light input surface 434
outwardly toward light emitting surface 436 which define radially
extending grooves or channels in light conduiting member 430. As best
seen in FIG. 31, side walls 438 and 440 preferably terminate before
reaching light emitting surface 436. Alternately, one or more light
conduiting portions may include respective side walls 438 and 440 that
extend from their respective light input surfaces 434 to their respective
light emitting surfaces 436. In this manner, light pipe 430 comprises a
plurality of discrete light transmitting or conduiting portions rather
than a unitary light conduiting or transmitting member.

[0107] Light sources 432 are positioned and, preferably, optically coupled
to light input surfaces 434 of each respective light transmitting or
conduiting portion 430a. Referring to FIGS. 31A and 31B, in the
illustrated embodiment, light sources 432 comprise surface light emitting
diodes (LEDs) and preferably comprise a flat rectangular wafer 432a with
a projecting emitter 432b, which are commercially available from the
Piranha line of Hewlett Packard. In preferred form, each light input
surface 434 includes a recess and, more preferably, a cylindrical groove
434a for receiving the respective light emitting portion 432b of the
light source 432. In this manner, the light emitters 432b of the
respective LEDs may achieve good optical coupling with light input
surfaces 434. Alternatively, each of the respective light input surfaces
434 of light transmitting conduiting portions 430a may include a
semi-spherical recess for receiving the respective light emitters of the
light sources 432, which will maximize the optical coupling between light
sources 432 and light conduiting portions. However, semi-spherical
recesses are harder to tool and to assembly.

[0108] Light input surfaces 434 of each light transmitting or conduiting
portion 430a are generally parallel or only slightly angled with respect
to its respective light emitting surface 436 such that the light emitted
from the respective light source 432 will project outwardly from light
emitting surface with minimal reflection inwardly from the light emitting
surface. Furthermore, sides 438 and 440 are angled with respect to light
input surface 434 such that light from light source 432 is internally
reflected and redirected outwardly from light emitting surface 436. In so
doing, light pipe 430 optimizes the internal reflection of each light
transmitting or conduiting portion 430a to efficiently direct the light
emitted from light source 432, which tends to project light in a cone
shape light pattern, outwardly through light emitting surface 436.

[0109] Signal light 416 preferably comprises a module which is preferably
removably inserted into a slotted opening or recess 412b formed in
housing 412 of exterior rearview mirror assembly 410. Preferably, signal
light 416 includes a lower housing portion 442 and an upper housing
portion or cover 444. Upper housing portion 444 may be secured to lower
housing portion 442 by conventional fasteners, for example fasteners,
including screws, snap-fit couplers, or the like, such that light sources
432 are serviceable, or may be welded or adhered to housing 442, for
example by sonic welding, heat staking, or an adhesive, so that signal
light 416 can be replaced as a unit. Light conduiting member 430 is
positioned in lower housing portion 442 and is preferably integrally
molded with housing portion 442 such that light emitting surface or
surfaces 436 of light pipe 430 form a portion of the outer perimeter wall
446. However, it should be understood that light conduiting member 430
may be separately formed from housing portion 442 and, instead, inserted
into housing and positioned such that light emitting surface or surfaces
436 is optically coupled to perimeter wall 446.

[0110] In preferred form, lower housing portion 442 is formed or molded
from a clear plastic, including for example polycarbonate, acrylic, or
the like. In contrast, upper housing portion 444 may comprise any
suitable plastic, for example a melt-processible plastic or moldable
material, such as described in reference to casing 212. Furthermore,
upper housing portion 444 may be opaque.

[0111] Each of the respective light sources 432 includes electrical wiring
447, which extends through housing 442 and through an opening 448
provided in perimeter wall 446 of housing 442. Optionally, perimeter wall
448 may include an electrical outlet or plug to which the electrical
wiring is coupled for coupling to the electrical system of the vehicle.
In addition, light sources 432 may be coupled to and powered by a circuit
board mounted in housing 442, which is electrically coupled to the
electrical system of the vehicle. Furthermore, light sources 432 may be
powered by flexible circuitry, which is electrically coupled to the
electrical system of the vehicle, or any other suitable conventional
power supply system. Alternately, each individual wire may project from
housing 442 for individually coupling to the electrical system of the
vehicle.

[0112] As best seen in FIG. 31, upper housing portion 444 includes one or
more retaining clips 450 for securing to a corresponding structure
provided in housing 412. In the illustrated embodiment, retaining members
450 comprises conventional bayonet or snap type couplers, but it should
be understood that other couplers, such as threaded fasteners, or the
like, may be used. As described in preferred form, light conduiting or
transmitting portions 430a rely on internal reflections of the light
emitted from light sources 432 to transmit or conduit the light from
light source to light emitting surfaces 436. In this manner, light
conduiting member 430 is easy to manufacture and assembly and relies on
the geometry of the light input surfaces and side walls in order to
produce an effective signal light 416 rather than reflections from
reflective surfaces. However, it should be understood, that side walls
438 and 440 may include reflective surfaces, such as vacuum metalized
surfaces or the like. However, this would entail additional manufacturing
steps and require more careful handling of the article and, consequently,
would increase the cost of the signal light 416.

[0114] As best seen in FIG. 32B, a third embodiment 416'' of signal light
includes a single light source 432'' such as a conventional light bulb to
emit light for input into the respective light input surfaces 434'' of
each respective light conduiting portion 430a'' of light pipe 430''.

[0115] It should be understood from the foregoing, that light pipes 430,
430', and 430'' are formed with respective side walls 438 and 440, 438'
and 440', and 438'' and 440'' to guide the light from the respective
light source or light sources 432, 432', 432'', to the outboard edge 431,
431', 431'' of light pipe 430 to form a signal light which directs light
rearwardly, laterally, and forwardly of the vehicle. Whether light pipes
430, 430', 430'' are formed as a single unit with a plurality of light
transmitting or conduiting portions 430a, 430a', 430a'', or as a
collection of discrete light transmitting or conduiting portions, in
which case discrete regions of light will be produced, signal lights 416,
416', and 416'' provide simple and inexpensive light assemblies which are
easy to manufacture and install.

[0116] It should be understood that should it be desired to vary the
intensity of the signal lights so they are brightest during high ambient
lighting conditions, such as on a sunny day, but so that they are dimmer
when ambient conditions are lower, such as at night, the intensity of the
signal lights can be modulated using a photosensor such as a
photoresistor, photodiode, phototransistor, or their like. A photosensor
that controls the intensity of the signal light so that it reduces its
intensity during low ambient light driving conditions, such as by pulse
width modulation on the electrical line powering the LEDs in the signal
light, may be mounted integrally with the signal light module itself, or
it may be part of the vehicle electronics itself, such as a photosensor
mounted as a part of an automatic electrochromic mirror circuit, as part
of a vehicle automatic headlamp activation circuit, as part of a headlamp
daylight running light control circuit, or their like.

[0117] Referring to FIGS. 33-37, the numeral 510 designates a fourth
embodiment of the exterior rearview assembly of the present invention.
Exterior rearview assembly 510 comprises a powerfold exterior rearview
mirror assembly and includes a housing or casing 512 in which a
reflective element 514 is supported. Reflective element 514 is optionally
supported in casing 512 in a similar manner to that described in
reference to the earlier embodiment and, therefore, reference is made
therein for further mounting details and, additionally, for examples of
reflective elements which can be employed. In preferred form, exterior
rearview assembly 510 includes a "powerfold" mechanism that is typically
operated and actuatable/deactuatable from within the vehicle cabin either
by a user operator switch or by a speed sensor that folds the mirror out
when a predetermined vehicle velocity is sensed and that upon activation
by the driver causes a folding portion 510a of exterior mirror assembly
510, for example casing 512, to fold or move or pivot about a fold-away
axis 511 on a non-folding portion 510b of exterior mirror assembly 510,
for example a mounting bracket or the like, from its normally extended
viewing position wherein mirror assembly 510 provides a field of view to
a compact folded position wherein the rearwardly facing side of the
folding portion is disposed generally parallel to the vehicle body (FIGS.
34 and 35). "Powerfold" exterior rearview minors are conventional and,
therefore, the specific details of the "powerfold" mechanisms are omitted
herein. In many European countries, "powerfold" exterior rearview mirror
assemblies are used during parking to reduce the width of the vehicle.

[0118] In addition, exterior rearview mirror assembly 510 includes a
security light and, preferably, a self-contained, unitary security light
module 516 which in the illustrated embodiment is mounted to folding
portion 510a of mirror assembly 510 on a bottom wall portion 526 of
casing wall 512a (FIG. 36). Security light 516 is preferably of similar
construction to unitary light module 200 described in pending application
entitled EXTERIOR VEHICLE SECURITY LIGHT Ser. No. 08/687,628, filed on
Jul. 26, 1996, by Todd W. Pastrick et al., now U.S. Pat. No. 5,823,654,
which is assigned to Donnelly Corporation of Holland, Mich. and which is
incorporated herein in its entirety. Security light 516 includes a
housing 518, in which a light source 520 and reflector 522 are supported,
and a cover or lens 524. Housing 518 is preferably a plastic material,
such as polycarbonate, polyester, nylon, acetal, polypropylene or ABS.
Cover 524 is optionally welded to housing 518, for example by sonic
welding, heat staking or the like, or adhesively attached by an adhesive.
Reflector 520 may comprise, for example a polished metal substrate, a
vacuum metalized substrate, or a metal filled substrate. As best seen in
FIG. 33-37, reflector 520 and lens 524 are adapted to direct light in a
light pattern 517. For further details of the components of security
light 516, reference is made to the above incorporated pending patent
application. As described in the referenced application, security light
516 is adapted to direct light generally rearwardly of the vehicle and to
fan out laterally from the vehicle to provide a lighted security zone
near or adjacent the vehicle. Furthermore, security light 516 is
preferably mounted in or substantially incorporated to casing 512 with
minimal protrusion from casing 512 into the slipstream such that security
light 516 does not add to the aerodynamic drag of minor assembly 510 and,
most preferably, with lens 524 substantially flush with the outer surface
of casing 512. Moreover, in preferred form, at least security light 516
or light source 520 is serviceable.

[0119] As best seen in FIGS. 34 and 35, security light 516 may be
optionally rotationally mounted in casing 512 such that when folding
portion 510a of exterior rearview mirror assembly 510 is moved to its
compact folded position, security light 516 remains in the same
orientation with respect to the vehicle such that the light pattern 517
which is projected from security light 516 remains substantially
unchanged despite the repositioning of exterior rearview mirror assembly
510. In other words, security light 516 remains stationary with respect
to vehicle V but rotates in casing 512 when exterior mirror assembly 510
moves to its folded position.

[0120] Referring to FIG. 36, security light 516 is mounted in an opening
512b in casing wall 512a. Security light 516 is mounted in opening 512b
by a rotatable sleeve or bushing 530 so that security light 516 is
rotatable about its axis 516a. In this manner, security light 512 is
movably or rotatably mounted in casing 512. Preferably, exterior mirror
assembly 510 includes an actuator or driver 528 such as a gear or other
suitable mechanism, including a servo-motor driver, a belt, a cylinder,
including a hydraulic or pneumatic cylinder, or the like, which
repositions or rotates security light 516 about axis 516a to maintain
light pattern 517 in a generally fixed position with respect to the
vehicle. As best seen in FIG. 36, gear 528 may engage threads 518a formed
on a lower portion of or a threaded collar mounted to housing 518.

[0121] Furthermore, exterior rearview mirror assembly 510 may also include
a break-away mounting which permits the exterior mirror assembly to fold
to a break-away position upon impact. Both of the powerfold and
break-away features are commonly known in the mirror art.

[0122] Alternately, security light 516 may be mounted in folding portion
510a in a fixed position; in which case, when folding portion 510a moves
to its folded position, security light 516 remains stationary with
respect to folding portion 510a but moves with respect to the vehicle. In
this embodiment, therefore, security light 516 is preferably oriented
such that it projects light to provide a security zone when folding
portion 510a is in its folded position, and preferably one that washes
the side of the vehicle and that provides adequate ground illumination
(an average of at least one lux ground illumination intensity desired, at
least five lux preferred) at the front and rear entrances/exits of the
vehicle where occupants may enter/exit the cabin. Typically, when a
driver of a vehicle with a powerfold exterior mirror approaches the
vehicle, the powerfold exterior mirror assembly is in its folded position
and does not move to its extended position until the driver is already in
the car with the ignition on. However, where the driver of the vehicle
uses a remote control for actuating the powerfold exterior mirror
assembly as the driver approaches the vehicle, the first embodiment of
the powerfold exterior mirror assembly may be preferred so that if the
folding portion of the mirror assembly is in its extended before the
driver enters the vehicle, then the security light will provide a lighted
security zone adjacent the vehicle which washes the side of vehicle and
provides ground illumination at the cabin entrances regardless of the
position of the folded portion of the mirror assembly.

[0123] Optionally, the exterior rearview mirror assembly may include a
proximity sensor 540 mounted on casing 512 which is electrically coupled
to the powerfold control system (not shown). Proximity sensor 540
actuates the powerfold function upon detection of an object, such as
another vehicle or wall, or the like. Furthermore, proximity detector 540
may be coupled with the light module control circuitry (not shown) so
that when the powerfold function is actuated by the detection of an
object, security light 516 will be similarly actuated to rotate with
respect to casing 512 to maintain light pattern 517 for the security zone
in substantially the same orientation.

[0124] Referring to FIG. 38, a fifth embodiment 610 of the exterior
rearview mirror assembly is illustrated. Exterior rearview mirror
assembly 610 is of similar construction to exterior rearview mirror
assembly 510 and also comprises a powerfold mirror assembly, Assembly 610
includes a folding portion 610a, which houses a reflective element 614,
and non-folding portion 610b, which is adapted to fixedly mount to the
vehicle body. Powerfold mirror assembly 610 is typically operated and
actuatable/deactuatable from within the vehicle cabin either by a user
operator switch or by a speed sensor as described in reference to the
previous embodiment. In preferred form, upon activation by the driver (or
by the speed sensor), folding portion 610a pivots or folds about a
fold-away axis 611 on non-folding portion 610b from its normal extended,
viewing position to a folded position wherein the rearwardly facing side
of exterior mirror assembly 610 is disposed generally parallel to the
side of the vehicle.

[0125] In this embodiment, a security light 616 is mounted in non-folding
portion 610b of assembly 610. Security light 616 is of similar
construction to security light 516 and, therefore, reference is made to
the previous embodiment for further details thereof. In this manner, when
folding portion 610a is moved between its extended position and its
folded position, security light 616 will provide a lighted security zone
adjacent the vehicle which washes the side of vehicle and provides ground
illumination at the cabin entrances regardless of the position of the
folded portion of the mirror assembly. Therefore, pattern of light 617
projected by light module 616 remains generally stationary with respect
to the vehicle and is unaffected by the repositioning of folding portion
610a of assembly 610.

[0126] Furthermore, as described in reference to the previous embodiments,
reflective element 614 may comprise an adjustable reflective element; for
example, assembly 610 may include a manual actuator or an electrical
actuator or the like, as should be understood by those skilled in the
art. Moreover, movement of reflective element 614 is independent of the
security light 616 as security light 616 is mounted or supported
independently of reflective element 614 to assembly 610.

[0127] As best seen in FIG. 38, security light 616 is preferably
substantially incorporated at non-folding portion 610b and
aerodynamically located into fixed portion 610b. Preferably, security
light 616 is incorporated into exterior mirror assembly 610 with minimum
protrusion into the slipstream of the mirror assembly. In this manner,
security light 616 does not significantly impact and, preferably, does
not add to the aerodynamic drag of exterior mirror assembly 610. Most
preferably, security light 616 is located into fixed portion 610b with
its security light lens 624 substantially flush with the outer surface
620 of folding portion 610b. Furthermore, in preferred form at least
security light 616, or its light source 620, is serviceable.

[0128] With regard to embodiments of this present invention that utilize a
security light module incorporated in a powerfold exterior mirror
assembly where the security light is located in the folding portion of
the powerfold assembly, the optical design of the light module can be
such that a pattern of ground illumination is provided, such as is
illustrated in FIGS. 11 and 12, and where the side of the vehicle and the
entrances/exits of the cabin are well illuminated, when the folding
portion of the powerfold assembly is retracted and folded to the side of
the vehicle body. Alternately, the preferred patterns of FIGS. 11 and 12
can be realized when the folding portion is extended to its outward,
non-retracted position. In this regard, it is optionally desirable that
the folding portion, if retracted and folded to the vehicle body when the
driver approaches the vehicle from a distance, can be remotely unfolded
such as by providing a button on a hand held transmitter (such as a
keyfob, commonly provided to vehicle owners today for remote lock/unlock
of vehicle doors) which, when actuated, transmits a signal, preferably a
radio frequency (RP) signal or an infrared (IR) signal, to a receiver in
the vehicle of which, upon receipt of the remote command, causes the
powerfold assembly to unfold and move its folding portion to the fully
extended, normal driving, unfolded position. Simultaneously, the security
light can be activated so that when the powerfold unit unfolds, the
signal light therein illuminates, and with both features being actuated
by remote actuation from a distance. Such feature or features can be
blocked out, as described previously, to avoid inadvertent operation when
the vehicle is in motion.

[0129] The concepts of this invention are applicable to a variety of
exterior vehicular mirror assembly constructions, including one-part
designs, uni-body constructions, and their like, as known in the exterior
mirror assembly art. The concepts of the invention are applicable to a
variety of assemblies including assemblies that use a bracket as a
distinct internal structure and assemblies that do not use a bracket but
rather are bracket-less assemblies where the housing itself serves as a
structural element with means such as on the walls of the housing for
securing an actuator and for receiving a lamp module.

[0130] Also, although desirably and preferably finding utility as a
security light, the exterior mirror assembly light modules of this
invention are also useful for other purposes such as providing for a
courtesy exterior light and a general ground illumination light when such
lighting may be desired such as when a door is opening, a key is
inserted, or a keyboard entry is touched, or when approach of a person to
a vehicle is detected such as by voice activation, proximity detection
and their like. Also, light modules using the principles and concepts
described herein could be provided for mounting on the vehicle other than
within an exterior mirror assembly, such as under a door within a door
well or under a door body panel so as to provide ground illumination
directly under a door whenever said door is opened.

[0131] While several forms of the invention have been shown and described,
other forms will now become apparent to those skilled in the art. For
example, the signal light assembly (216, 316, or 416) may project a white
light or other colored light including a red light or a blue light (such
as could be generated by a blue LED or blue phosphor). Likewise, the
security light module (516 or 616) may project a colored light, such as
an amber light or a red light as desired. Furthermore, as described in
reference to the first embodiment, rearview mirror assemblies 310, 410,
510 or 610 may comprise fixed position mirror assemblies or break-away
mirror assemblies. Changes and modification in the specifically described
embodiments can be carried out without departing from the principles of
the invention, which is intended to be limited only by the scope of the
appended claims, as interpreted according to the principles of patent law
including the doctrine of equivalents. Therefore, it will be understood
that the embodiment shown in the drawings described above are merely for
illustrated purposes only and are not intended to limit the scope of the
invention which is defined by the claims that follow.
